Abstract

Immersive navigation in virtual reality (VR) and augmented reality (AR) leverages physical locomotion through pose tracking of the head-mounted display. While this navigation modality is intuitive, regions of interest in the scene may suffer from occlusion and require significant viewpoint translation. Moreover, limited physical space and user mobility need to be taken into consideration. Some regions of interest may require viewpoints that are physically unreachable without less intuitive methods such as walking in-place or redirected walking. We propose a novel approach for increasing navigation efficiency in VR and AR using multiperspective visualization. Our approach samples occluded regions of interest from additional perspectives, which are integrated seamlessly into the user's perspective. This approach improves navigation efficiency by bringing simultaneously into view multiple regions of interest, allowing the user to explore more while moving less. We have conducted a user study that shows that our method brings significant performance improvement in VR and AR environments, on tasks that include tracking, matching, searching, and ambushing objects of interest.

摘要

虚拟现实(VR)和增强现实(AR)中的沉浸式导航通过对头显的姿态跟踪来利用身体运动。虽然这种导航方式很直观,但场景中的感兴趣区域可能会被遮挡,并且需要大幅度的视角转换。此外,还需要考虑有限的物理空间和用户移动性。有些感兴趣区域可能需要一些不太直观的方法(如原地行走或重定向行走)才能到达实际无法到达的视角。我们提出了一种使用多视角可视化提高VR和AR中导航效率的新方法。我们的方法从其他视角对被遮挡的感兴趣区域进行采样,并将其无缝集成到用户视角中。这种方法通过同时将多个感兴趣区域带入视野来提高导航效率,让用户在移动较少的情况下能探索更多内容。我们进行了一项用户研究,结果表明我们的方法在VR和AR环境中,对于包括跟踪、匹配、搜索和伏击感兴趣对象的任务,能带来显著的性能提升。
